Estimating Demand Elasticities of Meat Demand in Slovakia 31
Hupkova, Daniela; Bielik, Peter.
This article focuses on assessing consumer beliefs, attitude and behaviour towards meat. The aim is to obtain estimates of price and income elasticity of meat demand in Slovakia. This report analyses pork, poultry and beef meat consumption in Slovakia according to the individual households’ social categories. The Household Budget Survey of the Slovak Statistical Office was used for period 1993-2007. The data consists of yearly observations of beef, pork and poultry consumption, average annual consumer prices of beef, pork and poultry meat and net income per capita. Knowing the values of demand elasticities for food is widely used to correct policy formation and analysing trade patterns all over the world, but especially in developing countries where food...

Estimation and testing of fixed-effect panel-data systems 31
Blackwell, J. Lloyd, III.
This paper describes how to specify, estimate, and test multiple-equation, fixed-effect, panel-data equations in Stata. By specifying the system of equations as seemingly unrelated regressions, Stata panel-data procedures worked seamlessly for estimation and testing of individual variable coefficients, but additional routines using test were needed for testing of individual equations and differences between equations.
Tipo: Journal Article Palavras-chave: Panel data; Fixed effect; Multiple equations; Seemingly unrelated regressions; Heteroskedasticity; Autocorrelation; Contemporaneous correlation; Tests of linear combinations; Research Methods/ Statistical Methods.

Excess Capital in Agricultural Production 31
Kumbhakar, Subal C.; Guan, Zhengfei; Oude Lansink, Alfons G.J.M..
In this article we propose a theoretical model for analyzing capital requirement in agricultural production and define excess capital thereupon. We develop a two-step method that allows endogenous regressors in the maximum likelihood estimation. The two-step procedure is also capably of recovering the parameters of time invariant variables in fixed effect models. The model and method are applied to a capital requirement study using data from cash crop farms in the Netherlands. Empirical results show that excess capital widely exists on the farm. The implications of excess capital are further demonstrated with a production frontier analysis.

Seasonality and Costs of Production on Irish dairy farms from 2000-2007 31
Smyth, Paul; Harte, Laurence; Hennessy, Thia C..
This paper examines the relationship between calving date and production costs on Irish dairy farms from 2000-2007. Using data from the National Farm Survey, the median calving dates of 400 dairy farms are studied each year using econometric analysis to determine the relationship between calving date and production costs. Farms are divided into five categories according to their median calving date. These categories are imputed into a panel dataset as dummy variables. Unobservable individual effects are controlled for using a fixed effect model; examples of such effects are land quality and managerial ability, Results suggest that when scale and those unobserved effects are controlled for, there was no significant difference in total cost of production per...
